Technical characteristics of the Ceresit CT 17 primer and consumption rate per m2

Priming is an important step in renovation work. With the help of this procedure, it is possible to significantly improve the characteristics of the treated surfaces and increase their service life. To achieve the desired results, it is important to choose the right composition. Many craftsmen prefer Ceresit ST 17 primer, which has the best technical characteristics.

Composition and technical characteristics of the Ceresit CT 17 primer

Ceresit ST 17 soil is a universal water-dispersing substance. Its characteristic is considered a light yellow tint of the film. After drying, a characteristic shine appears on the surface. This makes the base easily recognizable even after complete polymerization. Also, the composition contains additional components - alkyd and ebonite resins, polymers, drying oil.

Due to the variety of components in the composition of the Ceresit floor, it provides a complex effect. The main properties of the substance are as follows:

  • Deep penetration ability. Thanks to this, the floor contributes to the qualitative strengthening of the treated base and turns into a component that binds particles of dust and dirt.
  • Reduced absorption properties of the coating. For this reason, using a primer can reduce the need for staining by 1 square meter.
  • No impact on the vapor permeability of the coatings.
  • Suitable for use on heated screeds.
  • Various forms of release. There are formulations for winter and summer on sale.
  • Increased lifespan of wallpaper and tile adhesives.
  • Possibility of applying plaster in a thin and uniform layer. The cracks linked to the drying out do not subsequently appear on the surface.

The composition is considered environmentally friendly. The instructions state that the primer is suitable for indoor and outdoor use.

Another conditional defect is considered a yellow tint. This allows you to identify unpainted areas, but sometimes causes difficulties when painting. Most often, problems arise when using white materials for decoration.

Also, the disadvantage of the primer is the complexity of its removal.If the mixture is poured on a surface, it can be difficult to clean. However, this drawback can hardly be called significant. With careful use of the material, the risk of these problems occurring is low. If the primer is used on linoleum, then it is worth protecting the surface from the penetration of the substance by covering it with a film.

In general, the advantages of a primer far outweigh the disadvantages. When using this material, it is possible to significantly improve the properties of the treated surface.

How to calculate material consumption

The recommended amount of soil per 1m2 is 150 milliliters. However, for old and porous surfaces, the dosage can be increased. In this case, 200 milliliters of substance are needed per m2. In the construction of online stores, there are often special online calculators that facilitate the process of calculating the required amount of the composition.

Tools needed for work

For preparatory work, it is necessary to prepare a putty composition, which is necessary for sealing seams and cracks. To protect windows, doors and baseboards from the primer, you need to use masking tape.For the use of the substance, it is recommended to prepare the following tools:

  • brush;
  • roll;
  • construction mixer - it can be replaced with a clean wooden stick;
  • paint palette;
  • a bucket of clean water.

Rules for surface preparation and working solution

Ceresit CT 17 primer can be used for the treatment of walls. This composition makes it possible to strengthen them. If the old coating is not firmly attached, it must be removed. It is recommended to tap the walls beforehand. This will help detect loose areas of the cast, which then need to be removed. If large cracks or depressions appear, they should be rubbed with putty.

At the stage of preparing surfaces for applying the primer, it is recommended to do the following:

  • Remove any visible traces of plaster, cement or other materials.
  • Remove all types of coatings. Exceptions are water-based and acrylic dyes.
  • Dry the walls thoroughly. After using the plaster, it will take at least 2 weeks, after applying putty - 1 day.
  • To avoid contamination of areas that do not need to be treated with soil, it is worth sticking paper tape in these places.
  • Get rid of mildew, oil stains and other blemishes.

Before using the primer, shake it sufficiently. It is recommended to thaw the winter solution in a warm room. Mix well before use. In this case, the composition does not need to be diluted.

Ceresit CT 17 Deep Penetration Primer Technique

When using a primer, you must strictly follow the instructions. Apply by roller, brush or brush. For highly absorbent substrates and anhydrite floors, it is recommended to apply the primer in 2 working passes.In this case, in the first case, it is necessary to apply a primer mixed in equal parts with water.

It is recommended to carry out further finishing work only after the primer mixture has completely dried. It takes an average of 4 to 6 hours. The specific time is determined by the drying conditions.

Immediately after the end of the work, it is recommended to rinse the tools with plenty of water. After drying, the primer can only be removed with a solvent.

It is important to take into account that it is recommended to carry out all work in dry conditions. In this case, the air and base temperature indicators should be + 5-35 degrees. Relative humidity should not exceed 80%.

It should be borne in mind that the floor slightly changes the shade of the treated base, causing its slight yellowing. This helps distinguish treated areas from untreated areas.

Drying time

The primer dries on average in 4-6 hours. In this case, the specific duration depends on a number of factors, the main of which is the temperature. The warmer it is in the room, the faster the coating dries.

Possible errors

When using the material, many novice craftsmen make a number of mistakes, which negatively affect the quality of the coating:

  • do not prepare the surface for the primer;
  • temperature and humidity parameters are neglected;
  • do not respect the drying time of the coats.

Security measures

Despite the relatively safe composition, the use of Ceresit CT 17 primer requires taking precautions. It is important to use personal protective equipment when applying the product. For this, it is recommended to use protective glasses, gloves, a mask or a respirator.This will help prevent the negative effects of the composition on the human body.

Also, when using a primer mixture, it is important to take into account that it is very difficult to wash off. Therefore, surfaces that are not intended to be primed should be covered. Windows, doors, baseboards should be sealed with adhesive tape.

Cost and storage conditions

The cost of a container with a volume of 10 liters is 600-700 rubles. Store the primer in a cool, dry place. This is best done on pallets. The composition should be kept in its original packaging and ensure that it is not damaged. It is important to protect the substance from freezing.

Recommendations from the masters

When using the Ceresit CT 17 primer mixture, it is important to adhere to the recommendations of experienced craftsmen. This will help you get the desired results. So, when applying a primer, consider the following:

  • It is necessary to store and work with the composition at a positive temperature. In this case, the parameters should be + 5-35 degrees. Humidity should not exceed 80%. Otherwise, the soil does not dry out. Any remaining moisture in the mixture will cause bubbles to form. The only exception is the special winter composition Ceresit ST 17. After freezing, the substance can be used. In this case, you need to thaw it gradually. To do this, it is enough to place the substance in a warm room.
  • When applying the primer, it is important to avoid puddles on horizontal surfaces. In this case, the streaks should not appear on the walls. The primer can be applied manually or using special devices. In the first case, a roller or brush is used, in the second - a compressor.
  • After applying a coat of primer, it must be completely dried before continuing work. It takes 4-6 hours. If the primer is applied to porous surfaces, it must be dried within 24 hours.
  • The quality of the layer can be evaluated experimentally. To do this, an adhesive composition or a dye in the form of a small grain can be applied to the dried surface and the dynamics of its drying can be assessed. If the material dries unevenly and this process is accompanied by the formation of light spots, it is recommended to apply another layer of primer. Materials with large pores must be treated twice with the product. Also, when applying the first coat, the primer should be diluted by half with water.
  • After drying and polymerization, the material acquires the properties of chemically inert materials and becomes insoluble. Therefore, it is recommended to rinse the tool with water after completion of work.

The use of Ceresit CT 17 primer allows to reduce the consumption of finishing materials, improve the quality of the coating and increase its service life. That is why this material is so popular.
